All Panda Security 2016 home user products for Windows are vulnerable to privilege escalation, CVE-2015-7378, which allows a local attacker to execute code as SYSTEM from any account (guest included), thus completely compromising the affected host.
High Level Details:
- CVE: CVE-2015-7378
- Vendor: Panda Security
- Reported by: Kyriakos Economou
- Date of Release: 05/04/2016
- Affected Products: Multiple
- Affected Version: Panda Security URL Filtering < v126.96.36.199
- Fixed Version: Panda Security URL Filtering v188.8.131.52
Panda Gold Protection 2016 v16.0.1

A local attacker can elevate his privileges from any user account and execute code as SYSTEM.
By default all the aforementioned products install (current version:184.108.40.206), which creates a service named ‘panda_url_filtering’ that runs as SYSTEM. The executable modules are by default installed in “C:ProgramDataPanda Security URL Filtering” directory. However, the ACLs assigned to the directory itself, and to the rest of the installed files, allow any user to modify those files and/or substitute them with malicious ones. A local attacker can easily execute code with SYSTEM account privileges by modifying or substituting the main executable module of this service, ‘Panda_URL_Filteringb.exe’, which will run at the next reboot of the host.
